Application filed February 21, 1914. Serial No. 820,096.

To all whom it may concern:

l 3e it known that I, RANDOLPH CROMPTON, a citizen of the United States,and a resident of Chatham, in the county of Barnstable and State ofMassachusetts, have invente an Improvement in Filling-Replenishingechanism for Looms, of which the following description, in connectionwith the accompanying drawings, is a specification, like characters onthe drawings representing like parts.

This invention relates to filling replenishing mechanism for looms. Ithas for an important object thereof the provision of novel means forautomatically supplying fresh filling carriers to the running shuttleswhen the filling carriers contained therein have become substantiallyexhausted or exhausted to a predetermined extent, or upon fillingfailure or breakage, and is particularly applicable to looms using aplurality of shuttles each carrying a distinctive filling carrier. Thus,in accordance with my invention replenishment occurs upon any one offourcontingencies which I group under the designation of filling fault in arunning shuttle.

In order that the principle of the inven tion may be readily understood,I have disclosed a single embodiment thereof in the accompanyingdrawings, wherein Figure 1 is a front elevation of a replenishing loom.embodying. my invention;

Fig. 16 .is a detail. in vertical section and end elevation of thereplenishing mechanism at the right hand end of the loom; and

Fig. 17 is a detail representing the Weft stopping mechanism.

In accordance with my invention, replenishment may occur upon fillingfailure or breakage, or upon substantial exhaustion, or exhaustion to apredetermined extent. I have herein chosen to indicate replenishment asoccurring upon exhaustion to a predetermined extent.

Any desired form of mechanism to indicate substantial exhaustion of thefilling in the running shuttle may be employed, as for example a fillindetector mechanism or a filling cutting o mechanism such as shown in myPatent No. 935,645, dated October 5, 1909. AI have, however, hereinillustrated measuring means to indicate a change of filling carrierswhen the filling carrier in the runningshuttle has become exhausted to apredetermined extent, although as above stated I am in no wise limitedthereto.

In the represented embodiment of my invention I have disclosed a loomhaving a magazine mounted adjacent to each end of the lay, there being aset of shifting shuttle boxes at one end of the lay, and a stationary orsingle shuttle box at, the opposite end Cir I thereof. I may and preferto use an ordinary self-threadin shuttle such as is customarily used inthe well-known Northrop looms and disclosed in the Northrop Patent, No.529,940, dated November 27, 1894.

Inasmuch as in the disclosed embodiment of the invention I employ twomagazines, one at each end of the lay, it is desirable to useself-threading shuttles of opposite hands. The pair of magazines mountedadjacent to the ends of the lav are herein so arranged as to receive thefilling carriers in both instances with their butts toward the center ofthe loom. To accon'iplish this, I have used, in this embodiment of theinvention, as above stated, right and left hand selfthreading shuttles.lVhen a change of filling carriers occurs at either end of the loom andwhen the shuttle is picked after replenishment has taken place, thefilling will be drawn into the threading eye of the shuttle in the usualway, except in case of rcplenislunent on the shifting shuttle box end ofthe loom where, as shown best in Fig. 9, the threading is accomplishedsimultaneously with transference. The two magazines, which, in thedisclosed embodiment of the invention, are at the, respective ends ofthe lay, together constitute filling supplying mechanism which, ashereinafter set forth, is under filling control to present fresh fillingcarriers one after another to complete exhaustion of the distinctivefilling carriers of said filling supplying mechanism.

In combination with the filling supplying mechanism thus broadlyexpressed, I provide filling carrier replenishing mechanism for thecarriers wound with distinctive filling including means to raise atleast one of a plurality of shuttles at one side only of the 100m froman operative position to an abnormal changing position.

The filling carriers may be bobbins or any other suitable supports.

Preferably and as herein disclosed, the magazine atone end of the loomis filled entirely with filling carriers all of the same distinctivecharacter, while the magazine at the other end of the loom is filledwith filling carriers of a different kind or character, but all thefilling carriers in each magazine are, in the disclosed embodiment ofthe invention, wound with filling of the same distinctive character.This distinctive character may be and preferably is one of color, but isnot necessarily such. lVhen the shuttle having the right hand threadinghead has exhausted its carrier to the predetermined extent and needsreplenishing, the magazine, which in the disclosed embodiment of theinvention is of the well-known Northrop type, operates in the usual wayafter being set for a change of filling carrier by the measuring means,which latter, as

previously stated, is preferably employed to indicate exhaustion of thefilling to the predetermined extent. When the shuttle having the lefthand threading head needs replenishing and after the measuring means hasregistered, owing to the exhaustion of the filling in that shuttle tothe predetermined extent, the box motion, which operates the shiftingshuttle box at the left hand end of the loom, is raised to a positionabove the highest position normally occurring during the ordinaryshifting of the shuttles to form the check or pattern. In being liftedto this abnormal or heightened position through the instrumentality ofthe box motion. which in the present case is preferably of thewell-known Crompton type, the filling carrier in the running shuttle,which occupies the top cell of the shifting shuttle boxes, is forcedagainst a filling carrier in the magazine adjacent to this end of theloom when the lay is approximately in its forward position. This actioncauses the substitution of a new filling carrier, the picking motionbeing preferably suspended during this operation,'and the magazine, asherein represented, turns two spaces during the backward motion of thelay and the lowering of the shuttle boxes.

As the magazine disclosed in this embodiment of the invention at theleft hand end of the loom is arranged to contain fifteen holders forfifteen filling carriers, it is obvious that two complete revolutions ofthe maga- 'zine will cause all the filling carriers to be positioned fortransference at this end of the lay.

The magazine at the plain or single shuttle box end of the lay is, inthe disclosed embodiment of the invention, turned to the extent of onefilling carrier at each move ment and exhausts itself after onerevolution, as is usual in all Northrop looms. Al-

though the disclosed embodiment of my invention contains two magazines,one at each end of the lay, it is to be understood that I am not limitedor restricted thereto, as within the broad scope and purpose of theinvention the filling supplying mechanism may be. variously positioned.Said two magazines together constitute one form or type of fillingsupplying mechanism adapted to contain fillin carriers of distinctive orcontrasting filing.

Referring more particularly to the disclosed embodiment of theinvention, the loom frame is indicated at 1 in the several figures. Thecam shaft is indicated at 2 and the crank shaft at 3, the former havingfast thereon a large gear 4 meshing with a smaller gear 5 fast uponthecrank shaft. The lav, which may be of usual form, is indicated at 6,it being connected to the crank shaft in the usual manner as byconnectors or links 7. Upon the crank shaft are mounted tight and loosepulleys in the usual manner, one of said pulleys being in.- dicated at 8in Fig. 14. A suitable belt shifter, Such as indicated at 9 in saidfigure, may be employed and operated in any usual manner not hereinnecessary to de scribe. 5

The cam shaft 2, as most clearly shown in Fig. 2, has fast thereon anarm 10 provided with a pin or stud 11 adapted to engage intermittentlyeach of a series of slots or sockets 12 in a mutilated master gear 13which is mounted upon a stud-14 upon a suitable stand or bracket 15secured to the loom frame. operating with the master gear to control ordetermine the movement of the shifting shuttle boxee, thereby to effectvnot only their norma movements during the usual working of the loom, butalso their abnormal movements to effect replenishment.

While for this purpose I may employ any suitable mechanism, I referablyemploy means codperatingwith t c said master gear 13 analogous tomechanism heretofore employed to control the shifting movement of ashuttle box in the normal running of the loom. c

For that purpose, I have herein repre sented two studs 16, 17 suitablymounted in the loomaframe and having fast thereon pinions 18, 19 meshingwith and adapted to be actuated intermittently b the teeth of the masterear 13 when a c 'ange of shuttle boxes is esired. The lower or left handstud 16, viewing Fig. 2, has fast thereon a disk 20 to which iseccentrically pivoted at 21 a link. 22;, the upper and opposite end ofwhich is pivoted to the shuttle box lever 23, the construction beingsuch that in the rotation of the inion 18, the shuttle box lever 23 isrocke upon its pivot. The upper and right hand stud 17 is rovided withan. eccentric upon which the s uttle box lever 23 is pivotally mounted,the opposite end 24 of said shuttle box lever being con nectedin anysuitable manner to the link 25 which at its lower end 26 is ivotallsecured to the shuttle box rod 2 said inks 25 being provided with asafety connection if desired and as thereinillustrated.

Each of the pinions 18 and 19 is rovided with a suitable forked hub 28,29 see Fig. 3) controlling the movement of sliding teeth 30, 31, whichmay be moved into and out of mesh with the teeth of the mutilated mastergear 13. The said sliding hubs and teeth are operated in any suitablemanner as by means of levers 32, 33 suitably mounted upon the loomframe.

The saidlever 33 is preferably operated through the medium of aconnecting rod 34 shown in Fig. 3, the opposite end of which I providesuitable means co -v isconnected to one arm 35 of an elbow lever pivotedupon the shaft 36 shown in side elevation in Fig. 4. Asshown mostclearly in Figs. 2 and 4, the pattern surface 37 of any suitable typesurrounds a pattern cylinder 38 having upon its inner end a ratchetwheel 39 engaged and adapted to be rotated by a pawl 40 which is pivotedupon a pawl carrier 41 itself pivotally mounted at 42 upon a suitablebracket. The opposite arm 43 of the pawl carrier is pivotally connectedto an upright link or rod 44 which at its lower end is suitably attachedto a lever 45 pivoted at 46 to a stand 47 upon the cross girt 48. Thelever 45 is preferably provided with a weight 49 by which it is held incontact with'a cam 50 fast upon the cam shaft 2.

The shifting or longitudinal movement of the connecting rod 34 by meansof the rocking of the shaft 36 causes the lever 33 to move the slidinghub 28 so as to bring the slidin tooth 31 of the pinion 19 into and outo mesh with the teeth of the master gear 13.

As shown in Fig. 2, a finger 51 pivoted at 52 upon a bracket rising fromthe loom frame rests upon the pattern surface 37 To the outer end ofsaid finger 51 is pivoted a link 52, the lower end whereof, as mostclearly indicated in Fig. 3, is pivotally connected to a crank arm 53which is itself pivoted at 54 co-axially with the lever 32, whereby thepattern surface 37 through the described connections shifts the hub 29and sliding tooth 30 of the-pinion 18 into and out of mesh with theteeth of the mastergear 13 as called for by the requirements of the.pattern.

Upon movement of the sliding tooth 30 into 1 pattern surface. Each ofsaid shuttle boxes, I as represented in said figures, is provided withshuttle binders 57, 58 respectively.

It is unnecessary to describe in detail the shuttle box motion itself,as it is-p referably of the well-known Crompton type-'1.

The up and down shifting moe'ment of the shuttle boxes in thenormaloperation of the loom is, as above described, effected through theinstrumentality of the pattern, mechanism acting to move the slidingtooth 30 into mesh with the master gear 13, and thereupon to rotate thepinion 18 without movement of the pinion 19. As will be hereinafterdescribed, the simultaneous movement of the pinions 18, 19 results inthe abnormal elevation of the shuttle boxes so as to effectreplenishment at the shifting shuttle box end of the loom.

I have heretofore stated that any suitable means may be employed to berendered ac-' tive upon substantial exhaustion of the filling orexhaustion thereof to a predetermined extent, and that in therepresented embodiment of the invention I have disclosed measuring meansfor the latter purpose and acting to count the picks made by eachshuttle.

I shall now describe one type of measuring means which may be employedfor this purpose, it being understood that other types of measuringmeans, or means rendered active upon substantial exhaustion of thefilling, or other means rendered active upon exhaustion to apredetermined extent may be employed instead, although my invention isnot in its broad aspects limited thereto.

Upon a suitable stud 59 mounted upon the loom frame, as shown mostclearly in Figs. 4, 5 and 10 to 13 inclusive, are loosely mounted twopairs of ratchet wheels 60, 61, 62 and 63 which are respectivelyoperated by forked pawls 64, 65 attached to the rocker arm 66 pivoted at67 upon a suitable stand 68 bolted to the loom frame. The rocker arm 66is adapted to be operated by a link or rod 69 which at its inner end ispivotally connected at 70 to one arm 71 of a bell crank lever pivotedupon a stud 72 mounted in a stand 73 upon the cross girt 48. Theopposite arm 74 of said lever is provided with a weight 75 by which thearm 71 is held in constant engagement with a cam 76 fast upon the camshaft 2, whereby upon rotation of said cam shaft the ratchets 60. 6]..62 and 63 are intermittently rotated. As stated, the ratchet wheels arearranged in two pairs and in the represented embodiment of theinvention, one ratchet of each pair is preferably provided withthirty-six teeth and the other ratchet with thirty-seven teeth. Thenumber of teeth should obviously be varied in accordance with the numberof yards of filling wound upon each of the filling carriers. Theratchets 60, 61, 62 and 63 are mounted between suitable friction blocks,certain of which are indicated in section at 77 in Fig. 10, and whichare restrained from rotation upon the stud 59 and are held in suitablefrictional engagement with said ratchets by means of the coil spring 78held in place by an adjustable collar 79 by which the tension of thespring and the consequent frictional engagement of the blocks with theratchets may be increased or diminished.

Each of said ratchet wheels has upon its 87 not being visible in Fig.10). Each of said openings is lessthan one half the width of the lowerend portion of the legs 88, 89, which as represented most clearly inFig. 10 rest upon said flanges. The pairs of openings 84, 85 and 86, 87when the loom is started are not in register, and the legs 88, 89 areconsequently supported by the respective flanges of the ratchet wheelsand cannot enter the openings until those pertaining to each leg comeinto register thereunder. The said openings will not register untilafter the ratchet wheels 60, 61, 62 and 63 have been rotated b -theirrespective pawls 64, the required number of times, which, in the presentinstance, is 1332 times; that is the multiple of the teeth in each setof ratchets. The said ratchet wheels are moved one tooth at every otherpick. The openings in the flanges will therefore not register in thedisclosed embodiment of the invention until 2664 picks of filling havebeen laid in the shed. Obviously the number of picks which the measuringdevice can determine may be varied by the use of larger ratchet wheelshaving more numerous ratchet teeth or by the use of smaller ratchetwheels having less ratchet teeth.

A more detailed description of the operation of this mechanism isunnecessary, inasmuch as it is substantially disclosed in the patentgranted to myself and another, No. 600,121, dated March 1, 1898.

After the determined number of icks has been wound off a carrier ineither 0 the running shuttles, the leg 88 or 89, acting in conjunctionwith the ratchet wheels pertaining to that particular shuttle, is forceddown by a sprin n90 into the openings which have been brpught intoregister, and the leg remains therein until the cam shaft 2,, is furtherrotated, whereupon the pawl 64 or 65 which operates the pair of ratchetwheels in question, cams or forces the leg out again into its normalposition as before, and as will be evident from the construction shownin Fig. 12 wherein the lower end of each leg is represented as beveledat 91 and wherein the flanges of the ratchets are represented as whichtakes under and is adapted to lift the lever arm 99 fast upon the shaft100 represented also in Fig. 16. The said shaft 100. is suitablyjournaled in the loom frame and preferably extends across the frontthereof from the measuring device end of the loom to the Single box endthereof where it is provided with a bunter 101 shown in dotted lines insaid Fig. 16, and which is normally held in depressed position by thecoil spring 102. The said bunter 101 cooperates with a suitablereplenishing mechanism co-acting with a ,single shuttle box and Which inFigs. 15 and 16 is shown as of the so-called Northrop type. Obviously,however, any other suitable replenishing mechanism for a single shuttlebox may be employed instead.

I have herein indicated the replenishing mechanism as of the so-calledNorthrop type, and it is unnecessary fully to describe the same indetail. As shown in said figure, the lay 6 is provided with a dagger 103co-acting with a suitable bunter 104 mounted at 105 upon thelreplenishing arm in such manner as to be inoved by the disclosed or anyother suitable connecting means into and out of the path of the dagger103, thereby to effect replenishment of tie shuttle in the single box106 in the usual manner upon the forward motion of the lay, whereby afilling carrier is transferred from the magazine 107 to the shuttle in awell-known manner.

At the shifting shuttle box end of the loom or left hand end, viewingFig. 1, is mounted a magazine 108, shown most clearly in Figs. 7 and.8,'preferably of the type shown in the atent granted to me, No.935,645, dated October 5, 1909. Below the said magazine is mountedpreferably in the usual manner the set of shifting shuttle boxes 55, 56previously referred to. These shuttle boxes are herein represented astwo in number, although obviously my invention is not restricted to anemployment of such number of shuttle boxes, inasmuch as within the scopeof my invention, a larger number of boxes may be employed. Between thesaid upper and lower boxes or cells 55 and 56, there is provided a space109 preferably corresponding in size to an ordinary shuttle box andhavmg an open side 110 through which a filling carrier, such asindicated at 111 in Figs. 7 and 8, may be discharged upon replenishment.The said space 109 is as represented without a binder and spring.

When a filling carrier in the left hand self-threading shuttle becomesexhausted to a predetermined extent as hereinbefore set forth, or uponfilling breakage or failure, or practical exhaustion, if mechanism forthat purpose be provided, as may be done within the scope of myinvention, the ratchet wheels 60, 61 controlling this magazine havebrought their openings 84, 85 into register or alinement, so that theleg 88 co-acting therewith enters the said openings, being forceddownward by the co-acting spring 90, as previously stated. The leg 88,which is mounted for sliding movement in the brackets or guides 93, 94,is pivotally connected at its upper end 112, as shown in Figs." 3 and10, to a link 113 pivoted at 114 to a lever arm 115 which is fast uponthe rock shaft 36.

Therefore, in this embodiment of the invention, upon exhaustion to apredetermined extent of the filling in a filling carrier pertaining tothe shifting shuttle box end of the loom, the shaft 36 is rockedsufficiently to rock the lever arm 35 and to move the connecting rod 34inwardly toward the center of the loom, or in the direction of the arrowthereon, thereby through the sliding hub 28 to move the sliding tooth 31into such position that it will be in mesh with the teeth of the mastergear 13, as previously described. The shaft 36 has also fast thereon adownwardly extending arm 116 which at its lower end 117 is pivotallyconnected t9 a longitudinally movable connecting rod 118 pivotallyconnected at its outer slotted end to a lever 32, the lower end of whichis connected to the sliding hub 29 controlling the movement of thesliding tooth 30 of the pinion 18, whereby the said sliding tooth isbrought into mesh with the teeth of the master gear 13.

Thus in the disclosed embodiment of the invention, upon practical orpredetermined exhaustion of a filling carrier pertaining to the shiftingshuttle box end of the loom, the shaft 36 is rocked so as thereby toplace the sliding teeth of both pinio-ns 18 and 19- into line with ormesh with the teeth of the master gear 13.

Thereupon both of said pinions will be rotated and by reason of the factthat the pivot of the shuttle box lever 23 is eccentrically mounted. theshuttle box rod through the described connections will lift the shuttleboxes abnormally, and will place the lower shuttle box or cell 56 onespace above the race of the lay instead of level with the race of thelay as heretofore, it being evident that the extent to which theshuttlebo-xcs are lifted may be varied in difi'erent types orembodiments of my invention. The shuttle box being abnormally positionedas described, the shuttle in the upper cell or box 55 is brought intocontact with one of the filling carriers 120 held in the magazine at theleft hand end of the loom as indicated in Fig. 7, whereupon the freshfilling carrier takes the place of the pxredeter-L minedlv'exhaustedfilling carrier, the latter being forced out through the open bottom ofthe shuttle box 55 into-the open space 109 between the two boxes orcells 55-, 56, thereby permitting said predeterminedly exhausted fillingcarrier to be discharged through the open side 110 thereof. From theforegoing description, it will be eyident that the filling carrierscontained "in the magazines at the two ends of the lay are cam 50.

presented one after another to complete or substantially completeexhaustion of the filling carriers contained therein. The fillingcarriers in the magazine 107,,shown in Figs. 15 and 16, are presentedone after another, so that all said filling carriers are exhaustedduring one rotation of the said magazine, and the filling carriers inthe magazine 108 at the opposite end of the lay are presented one afteranother, so that all said filling carriers are discharged from themagazine during two complete rotations of said magazine.

As most clearly shown in Fi 1 and 3, the shuttle box rod 27 is provid edwith an adjustable stop 121, whichwhen the rod is raised, strikesagainst one end of a. lever 122 suitably pivoted at 123 upon the pickingarm 124 and'havingat its other end a tooth or head 125 adapted normallyto en gage and upon the described movement of the lever 122 to bereleased from engagement with a finger .126 fast upon the shaft 127 ofthe picking arm 124. Thus, u onthe upward movement of the shuttle ox rodsufficiently to effect a change of fillin' carriers, the pickingoperation is suspende the picking arm 124 being permitted to. remainmotlonless upon t e' picking shaft The picker stick 128 willthereforeremain idle until. the box rod 27 is returned to working position afterthe filling carrier has been transferred as described. Thus one pick isomitted at the left hand end of the 00m.

The shaft 36, as most clearly shown in Figs. 4 and 5, is provided withan arched or curved portion 129 provided to clear the picking ball(omitted for the sake of clearness). The said curved portion 129 isprovided with a projection 130 which when the shaft isturned movesoutwardly under an adjustable stop 131 on the rod 44, the said rod inthe ordinary running of the loom imparting movement to the patternsurface as previously .desoribed. The engagement of the projection 130with the stop 131 arrests the operation of the rod 44, and therefore ofthe attern surfaccQinasmuch as the-lever 45 is t us held out ofengagement with the provided with an adjustable arm. 132 to whlch 1spivotally connected an arm' 133 of a bell crank lever pivoted at 134upon a bracket 135 upon the loom frame. The opposite arm 136 of saidlever is pivotallyconnected to a connecting rod 137, which at its outerend is pivotally connected to a lever 138, itself pivoted upon shaft139. Said shaft has fast thereon an arm 140 having a head 141 to takeunder and to rock the weft fork 142, thus suspending the loom stoppingfunction of the latter.

The weft fork hammer operates in conjunction with the weft fork andslide to stop the loom in the usual manner, and were not the operationof the Weft hammer suspended through the medium of the describedconnections, the loom would be stopped because of the omission of onepick during the described replenishment. In the manner described theweft hammer is held inoperative durin said omitted "pick and the loom isthere ore not stopped, but is kept in continuous operation without thepicking of filling during one revolution of the cam shaft 2.

As reviously set forth, the cam 76 on the cam s aft 2, through theconnecting rod 69 operates the pawls 64, and through the turningmovement of the ratchets 60, 61 forces the leg 88 upwardly out of itsopenings in the fianges of its said ratehet'wheels, owing to thedescribed beveled edge of the said openings, such movement occurringupon the next forward motion of the pawls 64, 65 following the movementwhereby the said openings were brought into register as above set forth.The leg 88 in resuming its normal position on the flanges of the ratchetwheel 60, 61 restores all the working parts to their normal position byreason of the return movement of rotation. thereby imparted to the shaft36. The shuttle boxes are thereby lowered into the position called forby the pattern surface just prior to the replenishing operatioriabovedescribed. The cam 76 for operating the ratchets 60, 61, 62, 63 iscireumferentially adjustable upon the cam shaft 2, so that it may be setthereon as the exigencies of correct'loom operation may require.

Simultaneously with the lowering of the shuttle boxes into runningposition, the'picking operation is restored inasmuch as the adjustablestop 121 is withdrawn from engagement with the lever 122, the head 125of said lever being restored to engagement with the finger 126 by meansof a suitable spring 143.

The pawls 64 and 65. are located over a suitable pawl lifter or camsurface 144 shown mostclearly in Figs. 2", 4 and 11. The said pawllifter 0r cam surface is pivoted at 145 upon a stand or bracket 146attached to the loom frame, as shown most clearly at the right of Fig.2. Mounted coaxially with the pawl lifter 144 is a lever arm 147, theouter end of which is pivotally connected as shown in Figs. 2 and 2 tothe .lower end of a link 148, the upper end whereof is pivotallyconnected at 149 to a the loom causes the lever 150 to be swung upwardlyupon its pivot and through the link 148'and lever arm 145 to turn thepawl lifter or cam surface 1-H so as to withdraw the flattened surface155 from beneath 'said pawls and thereby to lift the latter out ofengagement with their respective ratchets 60, 61, 62, 63.

The continued upward action of theshuttle boxes turns the cam surface14:45 until another flattened surface 156 is presented,

thereby lowering the pawl (it again into engagement with its respectiveratchets as best lndicated in Fig. 2. Thus on the next for- Ward motionof the cam on the cam shaft 2, the leg 88 will be raised out of theindex holes or openings 84:, 85, and as previously stated, the shuttleboxes will be lowered as previously described.

As I believe myself to be the first to devise a loom having meansadjacent to both ends of the lay to change for a fresh filling carrier asubstantially exhaustedfilling carrier or one exhausted to apredetermined ex tent, orlone the filling of which has failed or broken,and also to be the first to use or employ, in a loom operating aplurality of shuttles containing filling carriers differing in colors orother characteristics, filling supplying mechanism under filling controlto presentfresh filling carriers one after another to substantiallycomplete exhaustion of the distinctive filling carriers ofsaid fillingsupplying mechanism, and means to raise one of said shuttles from itsoperative position to an abnormal, changing position, to'e'ffect thesubstitution of a fresh filling carrier of the proper distinctivefilling for said running shuttle, in place of the running fillingcarrier in said shuttle, I desire to claim both of these featuresbroadly, however carriedout. one heretofore has ever, in a loomoperating with a plurality of distinctive fillings, lifted a shuttle boxor a shuttleto an abnormal, carrier-changing position, to effect achange of filling carriers in the said lifted shuttle.

lln certain of the claims, I have used the term ractical exhaustion tomean and to include both substantial exhaustion and exhaustion to apredetermined extent.

Having thus described one illustrative embodimentof my invention, Idesire it to be understood that although specific terms arefemployed,theyare used in a generic and descriptive senseand not for purposes ofSo far as I am aware, no

limitation, the scope of the invention being set forth in the followingclaims.

So far as I am aware, I am the first to provide a shifting shuttle boxloom wherein different colors of weft are supplied as called for by thepattern, with means to present fresh filling carriers of the properdistinctive filling one after another to complete exhaustion of saiddistinctive filling carriers and including means to raise one of aplurality of shuttles at one side only of the loom from its operativeposition to an abnormal changing position; to effect at said side of theloom the substitution of a fresh filling carrier of the properdistinctive filling pertaining to said raised running shuttle in placeof the running filling carrier in said shuttle. I, therefore, desire toclaim the same broadly, inasmuch as many,changes may be made within thescope of my invention, and as I may variously replenish the shuttlesother than the one herein referred to as raised from said operativeposition to an abnormal changing position, and am not limited to themeans herein shown, nor to such replenishment at the end of the layopposite that where the shifting shuttle boxes are positioned.
